Failed domain controller still listed as DNS server

Hello Experts,

I have two servers:

PDC = Server 2008 R2 = 'Server1' = 10.0.0.1
BDC = Server 2003 - 'Server2' = 10.0.0.2

there used to be another, which failed completely (replaced by Server 2008R2)
PDC = Server 2003 = 'Server3' = 10.0.0.3

The FSMO roles were successfully transferred and all of the ADUC, ADSS, DNS entries were cleaned up to remove Server3 as per MS documentation, however when I do an NSLOOKUP of the internal domain from any of the servers and PCs on the network, the IP address of the failed 'Server3' is still listed.

Can anyone suggest where else I should check for references to this server?  

Thank you in advance!

When you looked in DNS, did you look in the Name Servers?  If it was a DC, you can't just remove the A record, you have to go into the Name Servers and remove that instance.

Also, did you demote it correctly?  If not then there may still be metadata in place.  You can go in Sites and Services and check to see if the DC is located in there.

Hello cshepfam,

Yes, have removed entries from Name Servers tab in DNS.
No chance to demote it due to catastrophic RAID failure; Sites and Services has all been cleaned up according to MS documentation such as example below:

Have you checked for the entry in reverse lookups in your DNS as well?
Excellent, sorted! - I must've missed this several times when combing through the DNS entries as it didn't reference the server by name.

Thank you footech.
Glad to help.
